Building a Single Page Application using Ember.js ... for fun and profitBen Limmer
Denver Startup Week 2015 Talk. The talk is split into two sections: conceptual reasons you might choose a framework like EmberJS where convention over configuration is preferred, and a live coding demo where we build a simple EmberJS application for our up-and-coming business, Bluth's Banana Stand.
Testing Any Site With Cucumber and SeleniumChris Johnson
Do you have a website? Do you have any tests for that site? Even if you have unit tests integration tests can help you target workflows such as a checkout process. In this presentation I will talk about testing any site with Cucumber and Selenium. I will show what the tests look like, and explain the different ways to run these tests, from running them locally, building your own selenium grid to using Sauce labs as your testing infrastructure.
Service workers your applications never felt so goodChris Love
If you have not heard of service workers you must attend this session. Service Workers encompass new browser capabilities, along with shiny new version of AJAX called Fetch. If you have every wanted your web applications to experience many native application features, such as push notifications, service workers is the gateway to your happiness. Have you felt confused by application cache and going offline? Well service workers enable offline experiences in a much cleaner way. But that is not all! If you want to see some of the cool new, advanced web platform features that you will actually use come to this session!

JavaScript front end performance optimizationsChris Love
No one wants a slow loading, slow reacting application. As page weight has increased so has the dependency on JavaScript to drive rich user experiences. Today many pages load over 2MBs of JavaScript, but is this healthy? Do your scripts and dependencies perform well? In this session we will review common JavaScript performance bottlenecks, how to detect them and how to eliminate them.
This session will review common bad coding syntax, architecture and how to replace them with better alternatives. You will also be exposed to caching, code organization, build and deployment best practices that produce the best user experiences. Finally, you will see how to use the navigation timing and performance timing APIs to fine tune your applications to produce a fast, lean application your customers will love.
10 things you can do to speed up your web app today 2016Chris Love
Web Sites are to slow and this is costing businesses money. Most performance issues are easy to fix. In this session we review why web performance is important and 10 simple things you can do to make a faster user experience.
“How are business users assured that all features are built and tested?”. “Test cases written by the test teams are too technical for business users”. If you find yourself in the above situations, Behavior-Driven Development (BDD) may be a good choice for your team. In this presentation, we will discuss BDD as an agile development practice, automation testing using Cucumber as well as the advantages and disadvantages of BDD/Cucumber.

The average website loads over 1.5MBs of content per page, making over 75 requests. Many popular websites are serving over 5MBs just to load their homepages. And these numbers represent measurements taken AFTER compression is applied. The full weight of many popular websites is pushing 20+ MBs these days. In an era where performance truly matters to the end user experience, web developers need techniques to help curtail this bloat in data down the wire.
No matter how well you optimize, there is no better way than to delete things you do not need. How does one determine what is essential to the user experience and what is not? One answer Chris posits is to develop a hyper-lightweight version of your website which will provide critical insights into your specific performance priorities. This is a process that he has leveraged on many projects, in particular at YouTube to reduce the size of the video watch page from 1.5MBs to 100KBs. In this talk, Chris will take real-world web pages and show techniques for dramatically reducing their page weight and for identifying areas to optimize, while outlining the key steps to doing this well.
This talk will examine the two greatest problems in Ajax development (except for that pesky browser issue): Exactly what that “Asynchronous” word means, what problems it creates, and how they can be effectively managed, next the YUI Browser History object will be examined, finally handing control of Ajax applications back to the user via their familiar back button.
It's not the bugs you know that kill a website. It's the ones you can't see, lurking just out of sight, that get you. Learn how Lafayette College identified the Lovecraftian code horrors lurking beneath its feet with tools like Splunk (server log analysis), OSSEC (server-side bad behavior monitor) and SiteImprove (web page auditing tool) and then surgically eliminated the problems. Examples include PHP scripts spewing error notices into logs, undiscovered CAS authentication failures, and thumbnail generation scripts that choke on large files.

The Recording HTTP Proxy: Not Yet Another Messiah - Bulgaria PHP 2019Viktor Todorov
In our work we tend to believe in Messiah. A messiah can be the new magic tool which will solve all our problems, or a shiny framework, so much better than everything we have used before, or even a person in our team. We all know the messiah in software testing. It’s the Unit Testing. But is the unit test the one and the only way to test a software? The answer is no. This lecture will show you a new approach to software testing using a Recording HTTP Proxy and how it can help you achieve better quality of your software. Without proclaiming it as “The Great New Messiah”.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

42. Compiling, Testing, Distributing
• Apple developer account required to deploy
to iPhone
• Simulator can be different than actual device
operation, be sure to QA thoroughly
• Be prepared for a lengthy process of
registering, signing, deploying and obtaining
approval for your app
44. Really Like about iPhone Development
• Incomparable/exciting platform
• Standardized hardware, relatively powerful
device
• Cocoa and MVC paradigm
• “Bare metal” programming is a refreshing
change of pace
45. Really Don’t’ Like
• Objective C, iPhone application model
– Lots of assumed knowledge and undocumented rules
to discover
– Refactoring is difficult
• Xcode
– Code editor with GCC config… have come to expect
more
• App deployment
• Flaky connectivity
• Apple controlled domain
